EXCAVATOR AND LOADER APPARATUS.

Specification of Letters Patent.

Application filed June 17, 1913. Serial No. 774,211.

To all whom it may concern Be it known that I, GEORGE W. Burns, acitizen of the United States of America, residing at Cincinnati, in thecounty of Hamiltonand State of Ohio, have invented moved by theoperation of the engine cradle when it is desired to transport theexcavating machine.

Another obj vide an improved support for operating the scoop.

Another object of the invention is to so construct the excavatingmachine that it may be conveniently transported from one place toanother.

With these and other objects in view, this invention consists of certainnovel combinations, constructions and arrangements of parts as will behereinafter fully described and claimed.

This invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of the excavator with the inclined plane inan extended position. Fig. 2 is a side elevation of the excavator withthe inclined plane in a folded position and with the engine removed fromits support. Fig. 3 is an enlarged side elevation of a portion of theinclined plane in the position shown in Fig. 2. Fig. 4: is an enlargedfragmentary plan view showing the inclined plane in an extendedposition.

portion of the excavator. Fig. 6 is an enlarged sectional view of thelower end po'rtion of the inclined plane with the scoop at the lower endof the inclined plane.

Referring to the accompanying drawing, it will be seen that thisinvention comprises a frame providedv'ith supporting'wheels "It alsocomprises an incline plane leading to a tilting platform so that a scoopmay be drawn up the inclined plane onto the plato is a longitudinalsection through the rear form and tilt the sameto cause the dirt in thescoop to be dumped into a wagon posh. tioned beneath the platform.

When constructing this frame the plat;

. forms 10 and 11 are first built and are then connected with thesupport for the tilting platform which will be hereinafter described.Each of these platforms 10 and 11,

which I shall call the supporting platforms, comprlses the side beams 13having theirends connected by the cross-bars Hand connectedintermediatetheir length bythe bracing bars15 which carry the bearing blocks 16.Trucks 17 are positioned beneath the platforms lOand 11 and arepivotally connected with the platforms bythe king bolts 18 which passthrough the bearing blocks 16 into the bearing blocks, 19. Each of thesetrucks comprises a side bar 20 which are conect of the invention is topronected attheir ends by the cross-bars 21 and intermediate theirlengthsby the primary section of the bracing bars 22 supporting portingthe cross-bars 26.

The forward platform 10 carries the rear supporting standards 27 whichare connect- 1 ed with the shorter forward supporting standards 28 bythe connecting bars 29. These standards 27 and 28 carry the crossbars 30upon which the inner end portion3l' v i j of the inclined plane isrigidly secured,-as

shown in Fig. 5*. Longitudinally extending gulding strlps 32 arevsecured to the inner end portion 31 of the primary section of theinclined plane converge. to .guide the scoop and cause'it to leavetheinclined plane at the proper point.

The rear platform 11 carries the vertical standards 33 and 34:,whichstandards are braced by the cross-bars .35. 'Additional braces 36 areprovided for the standards 33 to prevent the standards 33 from movingout of thevertical position. It should be noted that the standards 34together with the cross-bars 35 and diagonal braces 36 form arectangular support which is hinged to the platform 11 by means of thehinges 371 so that the engine cradle may be releasably held in a raisedposition.

The engine cradle comprises longitudinally extending side bars 38pivotally connected with the standards-33 by means of the bolts 39 andconnected by meansofthe cross-bars 4O positioned at points through-Patented Nov. 10, 1914.

out their length. A fioorin 41 is built upon the frame formed from tielongitudinally extending side-bar's38 and crossbars 40 and carries a bed42 for the engine indicated in general at 43. Side rails 44 are providedto prevent danger of persons falling from the cradle. Therectangularsupport is held in a raised position by the securing pin 45',which is passed through one of the flooring boards into the upperbracingbar35 oftho hinged rectangular support. F roman inspection ofFig. 5 it will readily be seen that the hinged support holds the cradlein an elevated position when the-excavator is in use, but when thepin'45- is removed that the cradlemay be lowered to the dotted line positionshown so that the engine may be removed if desired.-

The upper platform connects the cross bars and and comprises thelongitudi nally extendingside bars 46 which are connected by the'crossbars 47 and flooring. 48 v This flooring- 48' is only provided at therear ortion of the upper latform; thus leaving an opening in the forwardportion in which openingthe -tilting platform, before referred to, ismounted. Diagonal braces 49 lead from the cross-bars 14 of theplatform-11' to the rear bracing bar 47 of the upper platform, thusstrengthening the frame and forming guides to prevent the cradle frommoving transversely. when being'raised or lowered. The upper platform isalso braced by the diagonal braces 49 and 49 Standards 50extendfromthe'upp'er platform and are connected by the shafts 51 uponwhich the pulley wheels 52 are mounted. These standards 50 are braced bythe diagonal bars 53 which bars have their lower endssecured tothecross-bars 54 and form supports for the inclined'board 55. This board"55 together with the inclined side boards 56' form a hopper extendingabout three sides of the opening: in which the tilt-' ing platform ispivotally mounted. The tilt-' ing platform '57 is' pivotally mounted inthe there are provided curved prongs 60 extending' above theuppersurfaceof the platform to steady the: scoop and prevent the scoop fromsliding from the platform.

The=upper portion of the'auxiliarysection of the inclined plane? ishinged to the lower end portion of the primary section and cornprisesthe flooring 61 which is pivotally connected with the side bars 31 bymeans of secured to the lower and upper portions of the primary andauxiliary sections of the inclined plane and pivotally connectedtogether, as shown in Figs. 3 and 4. This .flooring 61 is braced by thecross-bars 64 "which bars are connected by the truss-rod Guiding shoes66 are secured to the lower end portion of the flooring 61 and areprovided with downwardly curved points 67 which dig into the ground, asshown in F ig-.= 6, and: prevent the edge of the scoop fromeatchingv asthe scoop starts up "the inclined planer This scoop 68 isofthe usualtype used in excavating and is provided with the forward and rear yokes69 and 70 which yokes are pivotally connected with therear andforwardend portions of the scoop so that the scoop may be connected withthe'ends-ofthe line 71. This line 71 passes around a. pulley wheel- 72'carried by a stake 73 and after passing. over the pulley wheels52passes-around the'dru'm 74 of the engine. 1

VVhenthis deviceis to be transported to the place where it is to beused, the engine is removed from-the cradle and the auxiliary section ofthe inclined plane is folded as shown in Fig. 2. The forward and reartrucks are connected by the coupling shaft 75 at which time the devicemay be moved to any desired position. When the machine reaches a placewhere it is to be used, the coupling 75 isremoved and after the cradlehas been lowered to the dotted line position shown at Fig.- 5,-theengine is then putin place and the cradle raised to the elevatedposition. The auxiliary section of the inclined plane is then lowered tothe position shown in Fig. 1 with the points of the shoes digging intothe groundgand the line 71 is then passed overthe pulley wheels 52,- andafter one end portion has been passed around the pulley wheel 72 carriedby the stake -78 the'ends of the lines are connected with the yokes 69and 7 0.

The excavator is now ready for operation, and when the engine isstarted, the scoop will be draggedalong' the ground toward the inclinedplaner As the scoop passes along the groundit-is tilted sothat the dirtwill be scooped up-into the scoop until the auxiliary section of thescoop rests onthe inclined plane; When the forward edges of the scoopstrike the guiding shoes 66; the scoop will -be'caused to ride on to theinclined plane, and wilh thentravel on this plane until it reaches theupper plat-form- As soon as the scoop reaches the upper platthe upperplatform. Whenthe tilting platform tilts, the hopper built around theopening formed in the upper platform prevents the dirt from being thrownfrom the scoop upon the upper platform. It will thus be seen that thedirt will not gather upon this upper platform and make it necessary fora workman to climb onto the platform and shovelthe dirt from theplatform in the opening into the wagon. As soon as the scoop is emptied,the engine is started to rotate the drum in the opposite direction fromvthat in which it rotated when bringing the scoop up the inclined plane,and this will cause the scoop to be carried down the inclined plane tothe bottom where it can be again filled with dirt. As soon as the scoopleaves the tilting platform, this platform will return to its normalposition, shown in full lines in Fig. 5 c
